Abstract
The utility model discloses a clamping structure of a dry type transformer, and relates to the field of dry type transformer manufacturing. The clamping structure comprises an iron core, transformer plate type clamping element webs, pull belts, U-type screws, nuts and pull belt supporting plates welded to the upper edges and the lower edges of the transformer plate type clamping element webs. The pull belt supporting plates are provided with threaded holes, the U-type screws penetrate through the threaded holes in the pull belt supporting plates, the pull belts are connected with the tail ends of the two U-type screws so that the transformer plate type clamping element webs can clamp the whole iron core, the head ends of the U-type screws are provided with the nuts capable of facilitating adjustment of the clamping tightness of the iron core, buffering gaskets are arranged between the nuts and the pull belt supporting plates, and the pull belt supporting plates welded to the edges of the transformer plate type clamping element webs are vertically symmetric. According to the clamping structure, penetrating screws are replaced by pull belt tensioning structures, the iron core of the transformer is not punched, the magnetic flux of the whole iron core is uniform, no-load current and no-load loss are reduced, and operation noise of the transformer is lowered.
Description
Technical field
The utility model relates to dry-type transformer manufacture, relates in particular to a kind of clamping structure of dry-type transformer.
Background technology
Known in the industry, iron core is one of critical piece of transformer, and the transformer of board-like folder is all clamping with punching bar before, and folder web and the equal punching of iron core relative position, lock iron core with double threaded screw and nut.This structural disadvantages: iron core punching place total sectional area reduces, during transformer operation, magnetic flux density is large herein, makes in no-load current, no-load loss and increases, and transformer noise is large.
Utility model content
For the problems referred to above, the utility model provides a kind of clamping structure of dry-type transformer.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the clamping structure that a kind of dry-type transformer is provided, its structure comprises iron core, the board-like folder web of transformer, drawstring, U-shaped screw rod, nut and is welded in the drawstring support plate of lower limb on the board-like folder web of transformer, described drawstring support plate is provided with screwed hole, described U-shaped screw rod runs through the screwed hole on drawstring support plate, and described drawstring leads to the end that connects two U-shaped screw rods makes the board-like folder web of transformer clamp whole iron core.
Further, the head end of described U-shaped screw rod is provided with the convenient nut that clamps iron core tightness that regulates to root, between described nut and drawstring support plate, is provided with buffering spacer.
Root further, is welded in the drawstring support plate of the board-like folder web edge of described transformer for upper and lower symmetrical.
Root further, is provided with pad between the board-like folder web of transformer and iron core.
From the above-mentioned description to the utility model structure, compared to the prior art, the utlity model has following advantage:
1. cancel core through screw rod and change puller strap structure into, not punching of transformer core, the whole magnetic flux of iron core is even, and no-load current, no-load loss reduce.
2. by clamping mode, between the board-like folder web of transformer and iron core, be provided with pad, transformer operation noise is reduced.
Accompanying drawing explanation
The accompanying drawing that forms the application's a part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model is used for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:
